The KDP word-search maker

Generate a whole word-search book, then export it at every KDP trim, print-ready at 300 DPI. Make one puzzle free in your browser, unlock a full project for a one-time fee, and export unlimited formats forever.

Open Publisher StudioMake one free first

$4.99 once per project. Unlimited exports, every trim. No subscription.

A real generator, not a template

Paste a theme or a word list and the studio builds the grids, an AI-assisted word bank, de-duplication across puzzles and a matching answer key. A whole book is generated, not hand-placed cell by cell.

Every KDP trim, 300 DPI

Pick any KDP trim size, from 5.06 by 7.81 up to 8.27 by 11.69, with correct margins and gutter. Export a print-ready interior PDF and a separate answer-key PDF, each sized to KDP's interior spec.

Generate once, export forever

One project unlocks for $4.99. After that, re-export any trim, any time, as many formats as you like. No monthly subscription and nothing to cancel.

How it works

  1. 1Start with a free puzzle. Try the free generator in your browser to make one puzzle and its answer key, so you can see the output before you commit.
  2. 2Build the full book. In Publisher Studio, add your themes and words, or generate a word bank, and the studio lays out hundreds of puzzles with answer keys.
  3. 3Choose your KDP trim. Pick a trim size and format. The interior gutter scales with the page count, with correct margins and bleed for the trim, so it meets KDP's interior spec.
  4. 4Unlock once, export any size. Unlock the project for $4.99, then export the print-ready interior and answer-key PDFs at any trim, as often as you like.

Questions

How much does it cost?
A project unlocks for $4.99, paid once. After that you can export the interior and answer-key PDFs at any KDP trim, as many formats as you like, forever. There is no subscription.
What do I get when I export?
A print-ready 300 DPI interior PDF and a separate answer-key PDF, sized for the KDP trim you choose, with the margins and gutter KDP's interior spec requires. You upload them straight to KDP.
Can I try it before I pay?
Yes. The free word-search generator makes a real 2-page puzzle in your browser with no sign-up. The unlock is only for a full multi-puzzle project you plan to publish.
Can I sell the books I make?
Yes. The exported interiors are yours to publish and sell on Amazon KDP or print yourself. The per-project unlock covers unlimited exports of that project.
